Action Research week 2

I learned this week that it is important to utilize others research to gain knowledge about a specific problem and not to reinvent the wheel because someone out there has had the same issue you are having and has probably already discovered a reseanable solution.  You then can take that information and tweak it to your particular problem.  Then if that doesn't work you are already set up for an action research question, what is different about this situation that caused this solution not to be successful?
